I would love to see some easy built-in monetization system for PeerTube. Ideally this could be “micropayments” style subscriptions where you could pay a small amount to subscribe to a channel or a small-amount per video (with batched payments to avoid too high of fees). I would also love to see a “pay what you want” subscription option and tipping.

It would probably need to be plugable so that different payment providers can be used, but even just starting with one would be exciting.
